GAR-VENTILATOR.

Specification of Letters Patent. Patented N 23 1920,

Application filed November 19, 1917. Serial No. 202,790.

To all whom it may concern:

Be it known that I, l VILLIAM E. WINE, a citizen of the United States, residing at Toledo, in the county of Lucas and the State of Ohio, have invented new and useful Improvements in Car-Ventilators, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to a new and useful improvement in ventilators for freight cars, and to that type of ventilator shown in patent granted to me October 1st, 1912, hearing Serial Number 1,040,084, and patent of April 9th, 1912, Serial Number 1,022,918, which is now owned by the assignee of this applica tion.

The object of my invention is to provide a ventilator that incorporates all the advantages of my previous ventilator and with a further addition one that can be con-' structed largely of plates and rolled shapes.

With these and other objects hereinafter explained in View, my invention consists in the construction and combination of elements hereinafter described and claimed.

' In the accompanying drawings which illustrate the preferred embodiment of my invention; Figure 1 is a front view of the entire device when closed; Fig. 2 is a vertical section on line 2-2 of Fig. 1; Fig. 3 is an elevation of the portion of'the side frame of the ventilator; Fig. 4 is a section of the side frame on line 1-4 showing method of connecting cross bars to the side frame; Fig. 5 is a section of side frame on line 5-5; Fig. 6 is a perspective view of the shutters.

Similar characters designate similar parts throughout the several figures of the drawings.

Referring now to the parts by number: The frame is composed of sides 1, top bar 2, bottom bars 3 and 3 and intermediate bars 4. The openings between the top, bottom and intermediate bars are closed by shutters 5 which are provided with lugs 6 for connection with operating bar 7 by pin 8. The sides 1 are provided with slots 9 for the reception of the ends of the intermediate bars 4. The frame 1 is also provided with a flange 10 to which are riveted the top, bottom and intermediate bars by rivets 11.

The sides 1 are also provided with a guiding rib 12 in which are located pockets 13 and 1 1. The shutters 5-are provided with slots 15 at their opposite ends for the reception of ribs 12 on the sides 1. These shutters are also provided with an opening 16 through which the lugs 6 are attached there to by rivet 17..

The sides l are also provided with a rib 18 which seals the oint between the ends of shutters 5' and the side framel. At the upper end of rib 18 is a lug 19 extending horizontally from the sides 1 for supporting the upper edge of the shutters 5. This lug 19 is located at a sufficient distance from the top and intermediate bars so that the shutter 5 may be inserted there-between and above rib 12 until the notches 15 are in alinement with the outer edge of rib 12, then the outer edge of the shutters 5 can belowered into position shown in Fig. 2.

The connecting lugs 6 are of such length and proportions that when connected to operating bar 7, the, shutters 5 cannot be raised beyond their opened position shown in Fig. 2. g

It will be understood from this description that although the improvements in this invention are simple, they accomplish in a thorilghly practical manner all the objects soug I wish it further understood that I do not desire to be limited to the specific construction or arrangement of elements shown and described, as it is obvious that changes in construction and arrangement may be made without departing from the spirit of the invention.

Having thus described my invention, I aim in the appended claims to cover allrnodifications which do not involve a departure from its spirit and scope.

What I claim as new and desire to secure by Letters Patent of the United States is:
